The Coalition has reduced the amount of money it is spending on its Direct Action carbon reduction plan by more than $300 million.

The plan the Coalition took to the 2010 election was worth $3.2 billion, but just before Saturday's election the Coalition reduced it to just under $2.9 billion.

The biggest saving, $200 million, comes from halving the amount the Coalition plans to rebate consumers for installing solar panels and solar hot water systems.

The payment was supposed to be $1,000, but the Coalition says it is cutting it to $500 because the cost of the products has come down and it wants to target low income earners.

Almost $50 million will be saved by scrapping plans for three clean energy research centres.

The 2010 Direct Action policy said the Coalition would provide "$60 million to develop the La Trobe Valley, Hunter and Central Queensland regions as Clean Energy Employment Hubs to drive additional clean energy research and development".

Instead the Coalition says it will give $12 million to the National Climate Change Adaptation Research Facility at Griffith University on the Gold Coast.

Other savings come from spending money on solar energy projects over six years instead of four, and moving $50 million for geothermal and tidal energy projects to the industry budget.

Prime Minister-elect Tony Abbott this week instructed his department to begin drawing up the legislation to dump Labor's carbon pricing scheme, and says Federal Parliament will resume in late October or early November to deal with it.

Senior Labor MPs have already signalled the party will block moves to abolish the price on carbon.
